T 0 ctZZhuiLom it may concern? Be it known that I, EDWARD .11. Peru, a

citizen of the United States-"residing at Molina, in'tlie countyofRock Island and State of Illinois, have invented certain new and useful Improvements in a Vulcanizing Tool, of which the following is a specification. 7

My invention relates to vulcanizing tools, and has for its purpose to provide a simple 7 and efiicient instrument by means of which the inner tube of an automobile tire can be repaired, after being damaged. It is more specially designedto be carried on the vehicle, to 'be used on the roadin case of a blow-out, or other injury to a tire, but it is also well adapted for use in a private or public garage.

One of the purposes of the invention is to provide a means for holdingin place upon the inner tube what is commonly known as a patch while the vulcanizing operation is being performed. This is usually accomplished by the application of heat, and the tool is specially designed for use with that class of patches. It is equally useful, however, in attaching or cementing which are put on while cold. 7

Another purpose of the invention is to provide means for quickly positioning the tool on a section of the tube which is in need of repair, with the patch in proper place thereon, andas quickly releasing the patches same, after the work is done. It is also supplied with means for adjustment of the parts, so that it can be accommodated to differing thicknesses of material which is designed to be held thereby.

The above mentioned, and other features and advantages of the invention will more fully apear from the following specification, taken in connection with the accompanying drawings, in which:

Fig. 1 is a perspective of the invention, as

the same appears when in use.

Fig. 2 is a plan view thereof.

The invention comprises a circular plate 1, provided with a handle 2, and a frame 3, having an extension 4, which has a hinged connection with a projection 5 of the plate 1, by means of a threaded pin 6, pivoted in the part 5, as at a, and passing upwardly through an opening in the extension 4; The threaded end of the pin 6 is fitted with a wing-nut 7, by means of which the part 4 can be held in adjusted positions with relation to the part 5. The frame 3 correspoi'i'ds in shape and size with the plate 1, and is provided with a handle 8, fitted with an opening 9, to receive a toothed arm 15,

pivoted in the handle 2, as at Z. The teeth of the ram 10 are adaptedfor engagement with the handle 8, at the end of the opening 9, to hold said handle in locked relation with the handle 2.

11 represents a section of inner tube, in position'in the tool, and 12 a patch which is being held againstthe tube by the frame This patch usually consists of a small pan, containing inflammable matter, and a piece of rubber or other adhesive material, which is caused to adhere to the tube 11 upon the application of heat thereto.

lVhen the tool is being engaged with the tube, or being detached therefrom, the frame 3 can be tipped forwardly, at a right angle with the plate 1. In case the space between the plate 1 and frame 3 tightly grasp the section of tube, the parts can be brought closer together by adjustment of the nut 7. After the tubeis in place, with the patch in position thereon, the handles brought as near together as possible, and locked by the arm 10. After the parts are vulcanized, the arm 10 is released, and the tool removed. The operations of engaging the tool with the tire, and removis too great to minimum of time and labor.

The plate 1 is of a solid formation, to hold the tube snugly up against the patch, but the frame 3 is of an open formation, to permit for the combustion in the part 12. 7

What I claim, and desire to secure by Letters Patent, is:

1. A device of the class described, comprising a plate provided with a handle at one edge and a projection at its opposite edge; a frame similarin form to said plate, also fitted with a handle on one of its edges and a project-ion on its opposite edge; and a connecting member between said projections, having a hinged attachment with one of said projections, and provided with means for holding the other projection in adjusted positions with relation to the firstnamed projection.

2. A device of the class described, comprising a circular plate provided at one of its edges with a suitable handle and at the opposite edge with a coupling memher; a frame of similar form to said plate,

V also proyided with a handle on one of its edges, coinciding with said' firstnamed handle,'and on its opposite edge with acoupling member; coupling devices for saidnien'ibers, having ahinged connectionrwith one thereof, andhavlng a'nad ustable con,-

nection with the other one thereof; and connecting means for saidhandles, adapted to hold said plate and frame in a clamping position, and provided with means'of adjustment, to adapt said plate, and frame to ma- V terial of varying thicknesses. v In testimony whereof I afiix my signature.
